> In cold war it was obvious there were two sides ...
These two sides narration was a very intentional American construct. View from the other side wasn't symmetrical. US as seen from the other side was just seen as a powerful country that likes to mess around with other countries business exploiting them for their own purposes.
End of cold war changed nothing. US is still a powerful country that likes to mess around the world to exploit it better, and Russia is still insular country that doesn't want to allow any of that on their turf.
The only thing that changed with the end of the cold war was that US could no longer credibly spin the narrative that Russia wants to take over the world and turn Texans into communists.
Fortunately, after a bit of mucking around USA could brand terrorists as their global super dangerous enemy and business could continue as usual.
Currently when terrorists turned out to be a very limited threat and USA proved to be very incompetent at fighting them long term, USA again began shopping for a narrative enemy. Obvious choice is China, but USA leaders with more than two brain cells are little hesitant about that, because you don't necessarily want to frame yourself as enemy of someone who could very likely seriously eff you up.
We'll see how it all unfolds.
